This invention relates to improvements in ironing machines. Theprincipal object of the invention is to provide an ironing machine thatis of very simple construction,

of maximum efliciency in operation and that is cheap to manufacture. Afurther object is to provide a machine of this type in which thecooperating ironing members are moved into and out of engagement by thesame power employed to drive the machine thus giving the operator theminimum amount of work in connection with the operation of the machineand allowing him the freedom of his hands at all times as the machineneed not be touched by the operators hands to stop-or start it. I lViththe foregoing and other objects in view the invention consists inthecombination and arrangement of parts to behereinafter fullydescribed, pointed'out in the appended claims and illustrated in theaccompanying drawings which form 'a part of this specification and inwhich-- Fig. 1' is a plan view,'partly in section, of r the machine withthe housing removed.

Fig. 2 is an end elevation with the housing partly broken.

Fig. 3 is a fragmentary view of a slightly modified form of the machine.

Fig. 4 is an enlarged fragmentary view, partly in section, of one of thesprings and connections employed. 1

Fig. 5 is an enlarged fragmentary view I partly in section.

Fig. 6 is a perspective view of a pinion employed. v Like referencecharacters denote correspending parts throughout the severalviews.

The' machine comprises the. stand formed of the two lateral members 1connected by the rods 2, said stand carrying the receiving table 3whereon the frame 4 is carried that is provided with the feedtable 5.Secured to and carried by the frame 4 is the stationary shoe 6 ofconvexo-concave formation and extending longitudinally through the shoeand journaled in bearings 7 thereof is the rotary shaft 8. Loose'uponthe shaft outside the shoe is a pinion 9 which is recessed upon onelateral face to afford clearance for a clutch section .10 which is fastupon the said shaft-8 andwhich clutch section is adapted for releasableengagement with .the clutch section 11.loose upon shaft 8 and slidablykeyed to a worm gear,12

which encircles said shaft and is loose. there upon. "The worm gear 12is in' mesh with the worm 13 of drive shaft 14 which shaft 18 providedterminally with the pulley and fly wheel 15 which is connected by belt16 w1th the pulley 17 of the motor shaft which shaft is driven by themotor 18 carried by f tinuously to said pinion. The clutch section 11 isformed with an annular rib 22 which is in engagement with a notch formedin the clutch shifter 23, one end 24 of said clutch shifter being inengagement with the longitudinally slotted port1onI25 of an end bearing26 which is adjustably secured to the frame 4 by the screws 27, theopposite end 28 of said-clutch shifter being bifurcated and engagedby abell-crank-lever, 29 fulerumed to a sup'port 30 secured to the frame 4,said bell-crank-lever-being connected by a cord 31 to a link 32 carriedby a'foot lever 33 fulcrumed to one of the connecting rods 2 of'th'estand, said cord 31 passing through; a plurality ofguide eyes 34. Theclutch shifter is yieldingly retained in such position as to normallykeep the clutch sections 10, 11 disengaged by means of the flat spring23 secured to the frame and bearing against the shifter. Anchor rings 34secured to thecord-31 serve to limit the movement of the same and topre-. vent sudden jerks being transmitted to the clutch shifter. p

The said shaft 8 is provided at its ex treme ends with the elongateddiscs 35, 36, each disc being provided atone end with a pin 37 and thedisc 35 being provided with the cam-shaped lugs 38 arranged at its endsupon one lateral face, the two lugs 38 being disposed upon oppositesides of the longitudinal center line of the disc. supports or is formedwith elongated bearings 39 wherein the roller shaft 40 is dis posed,said shaft being movable laterally in its hearings in a direction towardor away from the shoe 6. Fast upon the said shaft is the roller 41 andalso the gear 42 which members, in one position of the shaft in itsbearings, are adapted for engagement respectively with the shoe 6 andpinion 9. Loosely secured to the ends of shaft 40 are the threadedeye-bolts 43 which are connected to similar eye-bolts 44, carried by thedisc pins 37, by the powerful contractile springs 45, adjusting nuts 46serving to firm- 1y secure said springs and eye-bolts together, or saidsprings may be threaded upon the bolts as shown in Fig. 1. In the formof machine shown in Fig. 3 the springs 45 are of the expansion type andthe pinion 9 is in mesh, releasably, with the interiorly toothed gearwheel 42. The gearing in the machine here illustrated is disposed towardthe front of the machine while the gearing in the preferred form of thedevice is disposed toward the back of the machine as will be apparentfrom reference to the drawings.

The operation of the machine follows: The motor, when running, drivesthe pulley 15, worm shaft 14, worm gear. 12, clutch section 11 andpinion 9 continuously, clutch section 11 being keyed to the worm-gearand pinion 9 being formed with the lugs 21 engaging the clutch section11. While the clutch sections 10, 11 are disengaged, however, the shaft8 remains stationary. To drive the roller shaft and roller to perform,in connection with the shoe, the ironing operation the operatordepresses the pedal 33 which meshes the clutch sections 10, 11 throughthe medium of cord 31, bell crank 29 and clutch shifter-23. Justprevious to the act of depressing the pedal the machine is in theposition illustrated in Fig. 1 with the roller and shoe, and the pinion9 and gear wheel 42 disengaged. When the shaft 8 makes one half of onerevolution the discs 35, 36 have moved through an arc of 180 degrees andthe cam-shaped lug 38 adjacent the disc pin engages theclutch-shifter-end 24 and throws the same outward or in a direction toseparate the clutch sections when the shaft 8 will cease instantly torotate due to the resistance ofiered by the powerful springs 45 whichare then in alignment with the shafts 8,40 and the crank pins 37, thespring then being at its extreme tension or on dead center. The shoe androller, as well as the pinion 9 and gear 42 are now in engagement androtating continuously and will so remain until the operator againdepresses the pedal 33:.to again mesh the clutch sections. The ironingis done, of

The frame 4 course, by the roller and shoe while they are in engagement,the operator feeding the garments upon the roller in the usual manner.WVhen the operator depresses the pedal 33 while the pinion 9 and gear 42are in mesh the shaft 8 will rotate one half of one complete revolutionwhen the cam-shaped lug 38 remote from the disc pin 37 will engage theclutch shifter and again disengage the clutch sections thus stoppingshaft 8 the same in its bearings, foot controlled means whereby saidfirst named means may be made fast to its'shaft to cause a predeterminedmovement of the same, means whereby rotary movement of one of saidshafts will cause a movement of the other shaft laterally in itsbearings and subsequently arrest the rotary movement of said first namedshaft.
